IMPROVEMENT IN GRAIN-DRILLS.

@In Soehnle nimh tu in time ttters -Qtteut mit mating met at its smite,

TO ALL WHOM IT MAY CONCERN:

Be it known that'I, HIRAM PULSE; of St. Paul, Decatur county, Indiana, have invented a' new and use. ful Improvement in Grain-Drills; `and hereby declarethe following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings, vmaking part of this specification.

i My invention relates to-improvements upon the implement patented by me February 12, 1867; and consists inthe following device:

First. An arrangement of hopper or sliding door whereby the graincan be fed to the dropping mechanism without or Without screening. i I

Y Second. An adjustable device for the seed-regulating slide. I A

Third'.A A cross-bolt constructedwith six nuts for holding'the beams and stand-sheath in proper relative position, and affording attachments for draught-rods.

Fourth. An arrangement of slotted hangers or braclrets and segmental racks for adjusting the elevation of the rear wheel or tightening-belt at will. v

Fifth. My inventionfurther consists in notching the seeding-spouts attheir rear sides, in combination with winged shares and valvesvo'r faps, enabling'the grain to get underneath theearth, and to be properly covered thereby without danger ofthe seedirig-spoutsbecoming clogged.

Sixth. A cheat-drawer for catching and removing the cheat, chess, and other small grains.

Seventh. Anv arrangement of notched rod and spring for operating the adjustable clevis.

Eighth. A caster-Whee in front of the machine, adjustable in height, for the purpose of supporting the front end of the machine, and, in conjunctionl with the rear wheel, of regulating the penetration of the shares or drills. Y

In the accompanying drawings#- Figure 1 is a perspective view of a graindrill embodying my invention.

Figure 2 is a sectional view of the same. v

The beams A A constitute essentially the frame of my machine. They are joined togethenrmly at their front ends, and are connected by a cross-bolt, B, provided with six nuts, 1, 2, 3, 4, 5, 6. Projecting downward.

and forward from the cross-bolt B and' rear ends of beams A A', are the sheaths C G C, which carry at their rear sides conducting-tubes D for the grain, while'at the upper ends of C C are attached two'handles, E E. The construction and arrangement of spout H, revolvingI screen I, -grainchamber K, agitator L, ductsM, ground-wheelR, and transmitting mechanism S, are substantially the same as exhibited in my patent of Februery 12,1867.

The grain-box F is supported on the frame of the machine, and has' at its upper par-t a grainchamber, F', whose sloping door forms the chute` G down which the grain travels to the spout H. At the upper en d of the chute G a passage, G', lis provided, which ,is closednt will by door g, to allow ofthe grain being fed to the seed-dropping mechanism either'with'l or with or-.without passing through the screen I. When it is desired to *deposit the grain without' screening, the door g `isslidover on to'the' chute G, and the sliding gate y lowered to stop the passage II, so as to compel all the grain fed to the hopper to pass through the throat G at the front end of the screen-chamber F. The ventage of the ducts M' is regulated by a slide, O, operated by a-lever,

, P, which can be retained in any position securely' by means of .the screwp in the slotted bracket p', and' the slide Q permits of the supply being cutoff from therear of the machine. .The rod W, which operates the draught-adjusting mechanism X Z Z, is notched at w, to it over therod a, and is kept in the notches by means of spring f. `The eross-bolt'B, by means of `the six nuts 1, 2,3, 4, 5, 6, iirmly securestogether the centre sheath C and beams A A', besides securing an attachment, as shown, for the draughtfrod Y. J is an'odal-drawer for collecting the cheat and other small refuse that escapes-from the screen when in operation. The ventage of each seed-dropping duct D is notched at a, immediately in rear of shares N N N, and is provided with a` valve, n, and 'side shares or wings, n', for the purpose of preventing the clogging ofthe ducts, and for enabling the grain to get properly underneath the earth. The shaft of theirear wheel'R'is supported on brackets e* secured to the sheaths C G at c, the brackets being also supported-by slotted -segmental arcs r. By this device the wheel R can be elevatedand depressed at will, to regulate the working depth of the shares. This 'roses` 2 device nlso admits of the driving-belt S being tightened without changing the elevation of the wheel R. A casterwhecl, T, is provided at the front end of the machine, fitted to a slotted and adjustable support, which can be secured in any desired position by means of a bolt, V.

I claim herein as nem-and of iny invention- 1. The upper box or hopper F, havngthe two doors g g and throats II G', for optional discharge of the grain either through the screen or otherwise, as set forth.

2. The slides O and Q adjusting-'lever P, clamp p, and slotted harp', combined and arranged substantially as and for the purposes set forth. y

3. The cross-bolt :ind nuts 1 2,V 3, 4, 5, 6, in the described combination, with the beams A A", sheaths C C C, und draught-rod Y, for the purpose specied.

4. The slotted brackets tr and slotted segmental arcs r', in combination lWitlrthe rear wheel R and drivingbelt or chain S, as and for the purpose specied.

5. The notched spcuts D, in combination with the valves n and Winged shares N n', for the purpose described. i

6. In thel described combination with the screen Iend screen-chamber F of my grain-drill, I claim the removable drawer J, for the purpose specified.

7. The notched rod W w and springf, for the purpose speeied.

8. The caster-wheel T, slotted bracket U, and bolt Vj, for supporting the front end of the implement, in combination with the adjustable rear wheel R, as and ,for the purpose set forth.

In testimony of which invention I hereunto set my hand. l l
